I love Jim's layouts, they're so much fun to just look at. I started inking them and you can see the first attempt on my blog. http://calvinostudios.blogspot.com/2008/08/inked-george-liquor-setups.html

I've been concentrating on getting control over my ink lines like you suggested and wanted to get your opinion on them. Aside from working on Jim's layouts I also redid some of my sloppier inks in this post: http://calvinostudios.blogspot.com/2008/08/inking-my-attempt-at-cleaner-lines.html
